目的比较甘肃产药食同源物质黄芪、红芪中无机元素含量差异。方法使用电感耦合等离子体质谱法(inductively coupled plasma mass spectrometry,ICP-MS)分别测定黄芪、红芪中19种无机元素的含量,采用非参数检验分析两者中无机元素含量差...目的比较甘肃产药食同源物质黄芪、红芪中无机元素含量差异。方法使用电感耦合等离子体质谱法(inductively coupled plasma mass spectrometry,ICP-MS)分别测定黄芪、红芪中19种无机元素的含量,采用非参数检验分析两者中无机元素含量差异,采用向量夹角法比较元素含量相似度,采用主成分分析及相关性分析法确定黄芪、红芪的特征无机元素及元素间的协同或拮抗关系。结果黄芪、红芪中无机元素含量有显著差异(除Zn外)(P<0.01),且黄芪中的元素总含量及大部分元素(除Zn、Cr、Mo外)含量低于红芪,其中Ca、Mg、Al、Sr、Zn、Mn的含量都较高;向量夹角法的评价结果显示,黄芪、红芪中元素平均值相似度为0.946,中位值相似度为0.919;黄芪的特征无机元素有Li、Al、Ba、Ca、Mg、B、Be、Pb,红芪的特征元素为As、Cr、Co、Li、Be、Al、Mo;黄芪和红芪大多数元素至少与其他8种元素存在协同吸收。结论黄芪和红芪无机元素含量差异明显,Ba、Ca、Mg、B、Pb或As、Cr、Co、Mo元素可以作为区分黄芪和红芪的指标。展开更多
